Euclid's proposition shows that chords that are equally distant from the center are equal and vice versa. The guide then examines the structure of the proposition. The To reset the applet, press "r"...More: lessons, discussions, ratings, reviews,...

Euclid's proposition shows how to inscribe a given segment in a circle whose diameter is greater than or equal to the segment (making the segment a chord of the circle). The guide then examines the s...More: lessons, discussions, ratings, reviews,...

Euclid's proposition shows that two points on the circumference are connected by a segment within the circle. The guide then examines the structure of the proposition. The To reset the applet, press...More: lessons, discussions, ratings, reviews,...
